For example, the NaNo was extremely hard on me and I discovered quite a few things. Words wars are not my cup of tea at all. I mean, it's not like I can't write during words wars because I do and it works. My problem lies with the fact that words wars are made for people to try just to put the words on paper, ignore the faults and just write. It made me feel like I was vomiting words. Even with my weeks of writing to get back into writing, I still felt the stiffness of not using my writing muscles for almost one year.
I did it, something I fucking managed to get to 50,000 words. Then proceeded unto scrapping away about 40,000 words away because it felt like I was writing layer of poop upon layer of poop. I can't even blame my inspiration. My writing just felt off. Mind you, I haven't deleted the files, I just put them into an "Old" folder for potential future use but still, it's jarring.
That being said, since I'm stubborn and ridiculously obssessed with my NaNo, I finally managed to shape it into that doesn't make me bash my head against a wall (the technical aspect I mean, not the plot or the worldbuilding).
If you want to take a look at it, it's there. Mind you, it's a HP fanfic and full of OCs.
